(Noun) Also known as a Rotherham Rinse.

A post-ejaculatory contraceptive douche carried out by the male whilst still inside the female vagina. Immediately after ejaculation inside his lady, before withdrawing his still semi-tumescent penis, the gentleman urinates within her, sluicing out his spermy man-milk. Purported to be 80% effective, by someone, somewhere, probably (depending on volume of piss).
Shaniqua couldn’t be bothered with any of the usual contraceptive methods, and neither could Marlon. So right after his vinegar strokes, he did the gentlemanly thing of giving her a Doncaster Douche to sluice out his spooge.
